Ah, a shape with 5 sides is called a pentagon. Isn't that a lovely name? Just imagine all the beautiful things you can create with a pentagon in your artwork. Keep exploring and embracing different shapes, my friend.
A WRIGGLE.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
The equation for the perimeter of a shape depends on the shape itself. For a rectangle, the perimeter can be calculated using the formula: P = 2(l + w), where l is the length and w is the width. For a circle, the perimeter is called the circumference and can be found using the formula: C = 2πr, where r is the radius. For other shapes, such as triangles or irregular polygons, the perimeter is found by adding the lengths of all the sides.
4 - w = 7 subtract 4 from each side 4 - 4 - W = 7 - 4 - W = 3 divide both sides by - 1 ( remember, the implied coefficient of w is - 1 ) (- 1/- 1)w = 3/- 1 w = - 3 =======check in original equation 4 - (- 3) = 7 4 + 3 = 7 7 = 7 ========checks
